I fully agree with you, Steem is a great tool for nonprofit.
I am going further, I created a specific token for nonprofit on Bitshares. Each nonprofit or socially responsible enterprise who is joining the Ventureo network will receive a 100,000 Ventureo initial funding.

I also have created the @askanything account to upvote the questions of the newbies.

So we can work together to convince nonprofits to join our great community.
